“In any critical situation the forward move is a creative act.”
Internet Encyclopedia of Philosophy
Context: In the chessboard of life, the different pieces have powers which vary with the context and the possibilities of their combination are numerous and unpredictable. The sound player has a sense of right and feels that, if he does not follow it, he will be false to himself. In any critical situation the forward move is a creative act.

Thomas Babington Macaulay, On John Dryden (1828)

Context: In a word, the Barbarian is discoverable everywhere in this that he cannot make; that he can befog or destroy, but that he cannot sustain; and of every Barbarian in the decline or peril of every civilisation exactly that has been true.
We sit by and watch the Barbarian, we tolerate him; in the long stretches of peace we are not afraid.
We are tickled by his irreverence, his comic inversion of our old certitudes and our fixed creeds refreshes us: we laugh. But as we laugh we are watched by large and awful faces from beyond: and on these faces there is no smile.
